I have seen some of this discussion. I am afraid I have seen no
documented discussion revealing the reasoning behind fixing the TLA
length and fixing it at 13 bits. Frankly I have been surprised by the
sudden speed of the provider based addressing standardisation.
last year in regards to what is now RFC 2050 I asked the lawyers that
do work for the IESG what restrictions in flexibility we (the IETF) have
in the area of defining rules and technology that restricts ISP practices.
I was told that the only time we can be restrictive is when there is
no other technically reasonable option - I support Daniel here, if this
field is to be restricted to a specific length then we must have
very good technical reasons for doing so.
